Abstract

Systems, devices, and related methods for shaping near field interrogation signals are discussed herein. Some embodiments may provide for a spindle supported near field communication (NFC) device including a spindle configured to mount to a mounting surface, and a beam shaping NFC device. The beam shaping NFC device may include: a ferromagnetic component including a core portion, wherein the core portion defines a core cavity and the spindle is inserted within the core cavity; and a wire coil disposed around the core portion. The ferromagnetic component may be configured to concentrate near field interrogation signals generated by the wire coil toward a near field interrogation region and away from the mounting surface, or other components capable of causing interference or degradation of the near field interrogation signals.

First claim

That which is claimed:

1. A spindle supported near field communication (NFC) device, comprising:
a spindle configured to mount to a mounting surface; and
a beam shaping NFC device including:
a ferromagnetic component including:
a core portion, wherein the core portion defines a core cavity and the spindle is inserted within the core cavity;
a first flange portion; and
a second flange portion; and

a wire coil disposed around the core portion between the first flange portion and the second flange portion, wherein the ferromagnetic component concentrates near field interrogation signals generated by the wire coil toward a near field interrogation region and away from the mounting surface;

a ribbon supply spool configured to mechanically attach with a ribbon supply roll, the ribbon supply spool to rotate around the spindle; and
a bearing component configured to facilitate rotation of the ribbon supply spool around a spindle rod portion of the spindle, the bearing component including:
a bushing disposed between an exterior surface of the core cavity of the ferromagnetic component and the spindle;
a first washer disposed around the bushing;
a second washer disposed around the spindle; and
a bearing disposed around the spindle between the bushing and the second washer.

2. The spindle supported NFC device of claim 1 , wherein the near field interrogation signals maintain communication with a radio frequency identification (RFID) tag while the RFID tag rotates around the spindle and within the near field interrogation region.

3. The spindle supported NFC device of claim 1 , wherein the first flange portion of the ferromagnetic component promotes the concentration of the near field interrogation signals away from the mounting surface.

4. The spindle supported NFC device of claim 1 , wherein the ferromagnetic component promotes the concentration of the near field interrogation signals away from the spindle.

5. The spindle supported NFC device of claim 1 , wherein:
the beam shaping NFC device further includes a nonconductive bobbin component including a bobbin core portion defining a bobbin cavity;
the core portion of the ferromagnetic component is disposed within the bobbin cavity; and
the wire coil is disposed around the bobbin core portion.

6. The spindle supported NFC device of claim 1 , the ribbon supply roll including an RFID tag, wherein the near field interrogation signals maintain communication with the RFID tag while the RFID tag rotates around the spindle and within the near field interrogation region.

7. The spindle supported NFC device of claim 6 , wherein:
the ribbon supply roll further includes:
a ribbon supply core;
a ribbon; and
a foil trailer attached to an end of the ribbon, wherein the foil trailer is wrapped around the ribbon supply core and the ribbon is wrapped around foil trailer; and the RFID tag is disposed between the ribbon supply core and the foil trailer; and

the ferromagnetic component concentrates the near field interrogation signals generated by the wire coil at the near field interrogation region such that the near field interrogation signals, after propagating through the ribbon and foil trailer, satisfy an activation level of the RFID tag.

8. The spindle supported NFC device of claim 1 , wherein:
the ribbon supply spool defines a spool cavity and the beam shaping NFC device is disposed within the spool cavity; and
the ribbon supply spool defines a protective housing for the beam shaping NFC device when the beam shaping NFC device is disposed within the spool cavity.

9. The spindle supported NFC device of claim 1 , wherein:
the ribbon supply spool includes a hub portion and a spool portion;
the spool portion defines a spool cavity and the spindle is inserted within the spool cavity; and
the spool portion further includes a fin configured to mechanically secure the ribbon supply roll with the ribbon supply spool.

10. A printer, comprising:
a housing defining an interior surface of the printer;
a spindle supported NFC device mechanically secured with the interior surface, the spindle supported NFC device including:
a spindle configured to mount to the interior surface of the printer; and
a beam shaping NFC device including:
a ferromagnetic component including a core portion, a first flange portion and a second flange portion, wherein the core portion defines a core cavity and the spindle is inserted within the core cavity; and
a wire coil disposed around the core portion between the first and second flange portions of the ferromagnetic component, wherein the ferromagnetic component concentrates near field interrogation signals generated by the wire coil toward a near field interrogation region and away from the interior surface of the printer;

a ribbon supply spool configured to mechanically attach with a ribbon supply roll, the ribbon supply spool to rotate around the spindle; and
a bearing component configured to facilitate rotation of the ribbon supply spool around the spindle, wherein the bearing components includes:
a bushing disposed between the exterior surface of the core cavity of the ferromagnetic component and the spindle;
a first washer disposed around the bushing;
a second washer disposed around the spindle; and
a bearing disposed around the spindle between the bushing and the second washer.

11. The printer of claim 10 , wherein the near field interrogation signals maintain communication with an RFID tag located while the RFID tag rotates around the spindle within the near field interrogation region.

12. The printer of claim 10 , wherein the first flange portion of the ferromagnetic component promotes the concentration of the near field interrogation signals away from the interior surface of the printer.

13. The printer of claim 10 , wherein the ferromagnetic component promotes the concentration of the near field interrogation signals away from the spindle.

14. The printer of claim 10 , wherein:
the beam shaping NFC device further includes a nonconductive bobbin component including a bobbin core portion defining a bobbin cavity;
the core portion of the ferromagnetic component is disposed within the bobbin cavity; and
the wire coil is disposed around the bobbin core portion.

15. The printer of claim 10 , the ribbon supply roll including an RFID tag, wherein the near field interrogation signals maintain communication with the RFID tag while the RFID tag rotates around the spindle and within the near field interrogation region.

16. The printer of claim 15 , wherein:
the ribbon supply roll further includes:
a ribbon supply core;
a ribbon; and
a foil trailer attached to an end of the ribbon, wherein the foil trailer is wrapped around the ribbon supply core and the ribbon is wrapped around foil trailer; and

the RFID tag is disposed between the ribbon supply core and the foil trailer; and
the ferromagnetic component concentrates the near field interrogation signals generated by the wire coil at the near field interrogation region such that the near field interrogation signals, after propagating through the ribbon and foil trailer, satisfy an activation level of the RFID tag.

17. The printer of claim 10 , wherein:
the ribbon supply spool includes a hub portion and a spool portion;
the spool portion defines a spool cavity and the spindle is inserted within the spool cavity; and
the spool portion further defines a fin configured to mechanically secure the ribbon supply roll with the ribbon supply spool.
